Ok, I am gonna try next time. It just wags when I give some throttle, it wags maybe 3secs (not very strong though) before being centered again, it's not too bad. I read about decreasing the GAIN in the Tx, I have a DX7, I set it at 72% which is recommended for the GY401 in all the DX7. The thing is that it was working perfect, that is why I didn't want to touch the gain but I'll give it a try. If I do decrease... how much would be good???? Thanks.
